A Rogue's Company (Sparks & Bainbridge Mystery #3)

In Allison Montclair's A Rogue's Company, business becomes personal for the Right Sort Marriage Bureau when a new client, a brutal murder, two kidnappings, and the recently returned from Africa Lord Bainbridge threatens everything that one of the principals holds dear.

In London, 1946, the Right Sort Marriage Bureau is getting on its feet and expanding. Miss Iris Sparks and Mrs. Gwendolyn Bainbridge are making a go of it. That is until Lord Bainbridge—the widowed Gwen's father-in-law and legal guardian—returns from a business trip to Africa and threatens to undo everything important to her, even sending her six-year-old son away to a boarding school.

But there's more going on than that. A new client shows up at the agency, one whom Sparks and Bainbridge begin to suspect really has a secret agenda, somehow involving the Bainbridge family. A murder and a subsequent kidnapping sends Sparks to seek help from a dangerous quarter—and now their very survival is at stake.
